Goonch catfish not eating ?

[Sealslayer]

Hey everyone, reaching out for some help regarding my goonch catfish. I’ve had him or around 2 months at the beginning everything was fine as time went on he stopped eating as much. He will try and eat but very shortly after he will spit out the food any tips?

What are you feeding? How big is it? What’s your water change schedule? Can you post your water parameters?
